Project Setup

Initialize the foundation for your frontend project.

•

Initialize version control repository

Run git init, create a remote repository, and set up .gitignore.

•

Choose and configure package manager

Select npm, Yarn, or pnpm and initialize the project with a lockfile.

•

Set up linting and formatting

Install ESLint and Prettier, create config files, and add npm scripts for linting.

•

Configure module bundler or build tool

Set up Vite or Webpack with a basic config for development and production builds.

UI/UX Design

Plan the user interface and experience before writing code.

•

Create low-fidelity wireframes

Sketch wireframes for each page to outline layout and navigation.

•

Design high-fidelity mockups

Use Figma or Sketch to produce detailed visual designs.

•

Define design system tokens

Establish colors, spacing, typography, and shadow values as CSS variables.

•

Document reusable components

Add components to Storybook with usage notes and props documentation.

HTML & Semantics

Write meaningful, accessible markup that supports SEO and assistive tech.

•

Use semantic HTML5 elements

Replace divs with header, nav, main, section, article, footer where appropriate.

•

Ensure proper heading hierarchy

Structure headings from h1 to h6 without skipping levels.

•

Add ARIA labels and roles

Supplement native semantics with ARIA attributes for custom widgets.

•

Include essential SEO meta tags

Add title, description, viewport, and Open Graph tags for search and social sharing.

Styling & CSS

Apply maintainable, responsive styles that adapt to various devices.

Adopt a CSS methodology

Choose BEM, SMACSS, or similar and enforce naming consistency across the project.

Use a CSS preprocessor or PostCSS

Leverage Sass/SCSS for nesting, mixins, and functions; or PostCSS for autoprefixing.

JavaScript & Interactivity

Add dynamic behavior with modern, modular JavaScript.

Write modern JavaScript using ES6+ features

Use arrow functions, destructuring, spread/rest, and modules for cleaner code.

Organize code into reusable ES modules

Separate concerns by exporting functions, classes, or components from individual files.

•

Manage application state

Select Context API, Redux, or Vuex based on complexity and team familiarity.

•

Handle DOM events efficiently

Use event delegation, debounce, and throttle to prevent performance bottlenecks.

Testing, Build & Deployment

Ensure quality through testing and automate delivery to production.

•

Set up unit testing framework

Install Jest or Vitest and write tests for utility functions and components.

•

Conduct integration tests

Use React Testing Library or Vue Test Utils to test component interactions.

•

Configure end-to-end testing

Set up Cypress or Playwright to simulate user journeys and catch regressions.

•

Establish CI/CD pipeline

Create GitHub Actions workflow to run tests, build, and deploy on each push.
